Guys, don't argue with Andy. He built the damn thing, I think he has an idea of what USB is, and what his device is capable of.  >:(

My experience has been the same as most of you, it all comes down to how the device handles itself. Some do it well, some do not.

If you want to be sure to eek out that extra 10ms button press response time, then by all means hook to PS/2. I'm sure you'll notice that difference easily! :) All joking aside, use the interface you like best, or test it out and see what happens; make the judgement call based on your evaluations.

So do other people...this is a discussion board.  We are discussing.

You might be surprised.  But I'm curious, how did you arrive at that number?  Are you sure it's not less?  More?  Aren't you the least bit curious?  I'm sure some people are, even if you are not.

But I'm not making any claims about one over the other here.  Only pointing out some things that don't ring quite 100% based on what I have researched, and of course, provided links to.  If you noticed, what I posted came from MS and Crucial.  I'm guessing they know what they are talking about too!

Sound advice.  :)

Sarcasm (10ms) and directed replies (non-Mr. Keywiz) don't convey well on a message board. :)

OK, let me recap this. On the one hand we have a clear explanation (from someone who obviously knows his stuff) about how it does work. On the other hand we have some unsubstantiated (and vague) claims that in some theoretical case there might be problems.

If the only points are:
- if one hooks up a completely crappy USB device on the same bus as the I-PAC it might not work properly
- if you use some flakey keyboard drivers (other than the standard ones that obviously DO work) you might have a problem

then to me that seems like someone is grasping at straws to find some argument.

BTW, as an indication as to how fast things can change from PS/2 to USB; remember how fast the old DIN keyboard connectors were replaced by PS/2? That took 5 years or something?

Anyway, I'd like to thank Andy for clearing this up.

I didn't follow this response -

The "Sarcasm (10ms)" comment was presented by you in this response:

If you want to be sure to eek out that extra 10ms button press response time, then by all means hook to PS/2. I'm sure you'll notice that difference easily!  All joking aside, . . .

Since you said you were joking, I would classify that at sarcastic.  RandyT was (I think) merely trying to point out that while lots of people throw figures around, no one provides any qualitative evaluation of what is happening.

Directed replies are used all the time on this board as a method of stating whether you are answering what someone else said, what 2 or 3 others said, or making a statement to no one in particular - Get used to it.

What was meant by "(non-Mr.KeyWiz)"?  Are you saying that that part of the response does not refer to RandyT?  Are you talking about his replies to you?  Are you talking about his replies to Andy Warne?  Are you implying that he is not responsible for the KeyWiz?  What?
